ParticipantsWe aim to recruit 30 adolescents 12 to 17 years who are experiencing body dysmorphic disorder (BDD), as well as 30 adolescents with an anxiety disorder and 30 healthy adolescents as comparison groups.
What is InvolvedAll adolescents who participate in this study will receive a thorough assessment for BDD and other emotional and behavioural problems. The study will also compare a group of adolescents with BDD to a group of teenagers who have other anxiety problems, and another group who do not have any significant mental health problems (known as a control group).

Participation in this study involves attending two assessment sessions via videoconference and completing online questionnaires. More specifically:

1. The study involves a comprehensive diagnostic assessment, conducted as a structured interview with the parent and child via videoconference to determine whether the child meets criteria for BDD and/or other emotional disorders. Based on this interview, we will determine whether this study is suitable for your child.

2. All families who meet inclusion criteria based on the diagnostic assessment will then participate in a task-based assessment session involving (1) two cognitive tests including the Wisconsin Card Sorting Task and the Go/No-Go Task, and (2) three family discussion tasks between the parent and child.

3. Children and their parent/guardian who meet inclusion criteria for the study will also complete online questionnaires. The child questionnaires enquire about their anxiety and depression levels, body image concerns, daily functioning, perceptions of their parents’ parenting styles, and perceptions of their peer relationships. Parent questionnaires will enquire about their child’s anxiety and depression levels, daily functioning, and parents’ anxiety and depression levels, body image concerns and family history of psychiatric illness.

All assessment sessions will be conducted with the student investigator Cassie Lavell who is a trained clinical psychologist.
